4.4.3Deleting Events and Alarms

To delete events or alarms currently logged within your SmartCell ZX-250, use the delete events and delete alarms commands, respectively.

4.5PVC CONNECTIONS

The SmartCell ZX-250 supports Permanent Virtual Circuits (PVCs), both point-to-point and point-to-multipoint. Use PVCs to connect devices (that do not support SVCs) to a switch’s local client. Also, use PVCs to make connections through the SmartCell ZX-250 between devices that support only PVCs.

Use point-to-point PVCs to connect one end node to another for two-way communication. Use point-to-multipoint PVCs to connect a broadcast end node to a group of receiving end nodes; traffic is one way.

2p›F PVCs use traffic descriptors to define their traffic characteristics. If you are unfamiliar with traffic descriptors, see Section 4.6.1, “Traffic Descriptors.”
